This invention relates to an improvement in a connection device for awrist watch and has for its object to provide a means which shall form apart of the wrist-encircling member or band; which shall be expansibleto enable the wrist-encircling member to closely and properly fit thewrist, and which shall be of simple and sturdy construction.

A further object of the invention is to provide an expansible connectionmeans for wrist watch bracelets which shall be ornamental in appearanceand enable a bracelet of one size to fit wrists of varying diameterswithout requiring the usual adjusting means.

lVith these objects and such other objects as may hereinafter appear, inview, I have devised the particular arrangement of parts hereinafter setforth and more particularly pointed out in the claim appended hereto.

Reference is to be had to the accompanying drawings forming a parthereof in which Figure 1 is a plan view of my improved connectiondevice, showing a part of the wrist-encircling member of the watch;

Figure 2 is a view of the underside of the structure disclosed in Figure1;

Figure 3 is a perspective View of one end of the wrist band showing thespring-pressed yoke;

Figure 4 is a sectional view on the line 4 of Figure 1,looking in thedirection of the arrow; and

' Figure 5 is a sectional View on the line 55 of Figure 1, looking inthe direction of the arrows.

In the embodiment of my invention disclosed in the drawings, 1 indicatesthe body portion of the connection member. The same is capable of beingmade in many ornamental shapes. It is preferably made from sheet metaland may be set with precious stones if desired. For the purposes ofsimplicity in illustration, I have omitted all ornamental embellishmentsand have shown the body portion 1 as consisting of a shell-like memberhaving outwardly splayed arms 2 and 3 which are secured to or form anintegral part of a tubular member 4 that fits between the spaced lugs 5and 6 of a watch 7. A connection pin, not shown, passes through the tu-1929. Serial no. 368,469.

bular member'lz and thus secures the member 1 to'the watch in theconventionalmanner.

As heretofore stated, the member 1 is in the form of a hollow shell andsecured within it, or forming an integral part of it is an elongatedtubular member 8. This tubular member 8 contains a coil spring 9 whichhas one of its ends bearing against a closed end 15 and its opposite endresiliently pressing against a cross-bar 10 provided on a yokeshapedmember 16 that projects from the end of the wrist band 13. Said wristband 13 is shown in Figure 1 as being of articulated form, the sameconsisting of a number of linked elements 14. This or any other type ofwrist band may be readily used.

The cross-bar 10 provided on the yoke 16 is movable in slots 11 providedin the opposite side walls of the tubular spring-containing member 8.

From the foregoing, the manner in which my connection member operateswill be readily understood. The spring 9 normally tends to hold thedevice in its closed position as disclosed in Figures 1, 2 and 4 of thedrawmgs. In this position, the end 17 of the wrist band 13abuts againstthe end 18 of the body member 1. To expand the wrist band, it is simplydrawn outward against the tension of the spring 9 as indicated in dottedlines in Figure 2. The wrist band may be thus expanded to enable thesame to he slipped over the wrist.

Guide pins 19 extend between the sides of the tubular member 8 and theside walls of the member 1. These pins 19 enable the side arms of theyoke 16 to uniformly move back and forth as required when the wrist bandis expanded or contracted under the pressure of the spring 9.

As heretofore stated, the device may be made in many ornamental forms,and the mechanism is wholly consolidated within the shell-likeconnection member 1. It is of sturdy construction and unlikely to getout of order and even in case of breakage of the spring, it is notpossible for the parts of the wrist-encircling memberto separate so thatthe watch and wrist band cannot in any manner become lost.

What I claim is:

A device of the class described comprising a connection member having anopen-sided casing provided with a pair of side Walls, means on saidcasing for attachment to a wrist watch, a tubular spring-containerprovided on said connection member and exposed at the open side of thecasing, a wrist band, a yoke thereon provided with side armswhich liebetween the side walls ofthe casing and the spring-container, across-bar on said yoke, a pair of slots in the side Walls of thespring-container in which said cross 1 bar is movable, a spring Withinthe springcontainer exerting pressure on the cross bar,

and guide means extending across the open side of the casing between thespring-conta1ner and walls of the caslng for gmdmg V the side arms ofthe yoke during their sliding movement,
